1 Claim.

This invention relates to improvements in glass cleaners and has for its primary object to provide a device to clean glass, such as automobile Windshields, of bugs and hard, dried substances Without injury to the glass.

Another object of the invention is to provide a scraping block with a transversely grooved or serrated surface for the collection of dirt and grit having means for simultaneously supplying Water, or other suitable cleaning liquid, to the said surface by means of a sponge held in a recess in the scraping block.

Other objects of the invention are to provide a glass cleaner that is of simple construction, compact, durable, easy to operate and low in manufacturing cost.

The invention consists in the combination and arrangement of parts as hereinafter described and claimed, and will be best understood by reference to the accompanying drawing forming a part of this specification, in which:

Fig. 1 is a bottom elevation of the invention.

Fig. 2 is a side elevation of the invention showing, by dotted lines and section the method of supplying water to the surface of the scraper block by means of a sponge seated in a recess in the block.

Fig. 3 is a perspective view of the sponge or absorbent member.

Fig. 4 is a side sectional ring.

Referring now to the drawing in detail, it will be seen that the reference numeral i, Fig. 2 designates the wooden scraping block having the transversely grooved or serrated surface 2 formed by a plurality of criss-cross grooves or slots 3 formed by milling out the slots both lengthwise and breadthwise. The purpose of said slots being to provide spaces for receiving and collecting dirt and grit from the glass to be cleaned. Perforation 4 in the serrated surface provide a communication between said surface and a recess 5 in the opposite side of the view of the retaining block, into which a saturated sponge B is inserted for the purpose of supplying water or suitable liquid cleaner to the serrated surface 2. A retaining ring or washer I made of rubber or similar non-absorbent material, with an opening 8, is placed over the sponge and held in place by the lips 9 gripping the formed projection I 0 in the recess 5.

The upper side of block I is rounded off as shown in Fig. 2, as an tion while in use.

In cleaning glass the serrated surface of the block is applied thereto and the block moved briskly. By exerting a finger pressure upon the sponge through the opening in the retaining ring a quantity of liquid is forced through the perforations onto the serrated surface. This liquid serves to loosen and flush foreign material from the glass.

It is believed that the utility and advantages of a glass cleaner as constructed in this manner will be readily understood, and although the preferred form of construction is here shown, it is to be understood that minor changes in construction may be resorted to Without departing from the spirit of the invention as claimed in the claim.

I claim:

In a device of the kind described, a block formed with a cleaning surface at one side and with a sponge recess in the opposite side opening outwardly through an annularly constricted mouth, there being ducts connecting said sponge recess with said cleaning surface, and an elastic sponge retaining ring in the mouth of the sponge recess, the periphery of said ring being formed for releasably gripping the constricted margins of the mouth of the sponge recess, whereby a wet sponge may be seated in the recess subject to finger pressure for squeezing Water through said ducts to the cleaning surface of the block.
